Abstract: PURPOSE:To make it possible to generate very strong X-rays of which energy can be changed continuously from almost zero to the maximum energy by providing a conductor rod movable perpendicularly to a tube axis in a side connection hollow and providing central protruding parts facing each other with the movable conductor rod between them. CONSTITUTION:The titled device is provided with a plurality of accelerating hollows 1, 2, and a side connection hollow 10 for connecting electromagnetic energy between the adjacent hollows among the plurality of accelerating hollows, a movable conductor rod 9 is provided in the side connection hollow 10 perpendicularly to a tube axis, and central protruding parts 13, 14 are provided facing each other. By adjusting the position of the movable conductor rod 9, resonance is achieved on the same phase mode (where, however, a Z-coordinate axis is taken in the direction of the center axis of an accelerating tube), or resonance is achieved in the reverse phase mode (where the Z-coordinate axis is taken perpendicularly to the axis of the accelerating tube). Continuous energy values can thus be taken in a wide range from a low energy substantially similar to zero up to the maximum energy taking the whole length of the accelerating tube for the effective acceleration length.

IPC: G11C11/407
Filed: 1987-04-13
Abstract: PURPOSE:To lengthen a refreshing time and to prevent a wasteful power consumption by executing the boosting by the boosting circuit at the time of re-writing only when the voltage level of a word line driving signal detected by a comparing circuit is lower than a prescribed voltage level. CONSTITUTION:First, the inverse of RAS signal falls and a signal phiWL is raised to a power source voltage Vcc level at a time t1 by a word line driving signal phiWL generating circuit 2 to receive the inverse of the RAS signal. Simultaneously with this, by a phiWL boosting circuit 3 to receive the inverse of the RAS signal, the signal phiWL is boosted and made into the Vcc level or above. In accordance with an input signal S4 at a time t2 when the inverse of the RAS signal rises, the phiWL boosting circuit 3 executes the boosting at the time of a comparing reference voltage Vref>potential level VWL, and at the time of the Vref<VWL, any action is not executed. Thus, the boosting at the time of the completion of an active cycle is automatically executed as needed and thus, the refreshing time can be lengthened without consuming a wasteful power.
